MBR Checksum Error, what do I do?

MBR Checksum Error

Hey:

I have a Samsung GalaxyS 1 that was recently hijacked by a rogue app. The rogue app is: com.qihoo.security. This app took over when I tried to update the phone's "360 Security" app. It deleted the 360 Security app and now the rogue app runs constantly and I cannot delete it or remove it's files for it runs constantly thus disallowing access to any other app or files. 1. How can I remove this rogue app when I cannot access any other app or files? 2. Is there some way I could "tether" the phone, then "wipe" and reinstall another O.S.?
Appreciate Any Help:
Rick

2. Do a factory reset
3. Flash ROM using Odin
